Google Analytics

A free web analytics platform by Google that tracks website visitors, their behaviour, traffic sources, and conversion events.

Without analytics, you are flying blind. Google Analytics shows exactly where visitors come from, which pages lose them, and which drive sales, essential for any marketing decision.

You notice from GA that 70% of your traffic comes from a single Pinterest pin, but only 0.8% converts. You update the landing page the pin points to, and conversion doubles.
